METHODS: Rat mesenchymal stem cells at passage 3 were obtained under sterile condition, and divided into groups A-F. In group A, iodine ion was not added. In groups B-F, iodine ion at mass concentrations of 2, 55, 90, 125 and 2 500 mg/L was added respectively. An additional blank control group was established, and simultaneously the cells were induced into neuron-like cells with dimethyl sulphoxide.

无菌条件下取大鼠第3代间充质干细胞，分为A~F组：A组不加碘离子，B~F组中分别加入质量浓度为2，55，90，125和2 500 mg/L的碘离子，另设空白对照组，同时加化学诱导剂二甲基亚砜向神经元方向诱导分化。

The analysis of parents using AFLP markers showed that there were more than 3.96% background differences in heredity between parents, which were much more than theoretical value. It indicated that there was a large conservative region near male sterile genes within Tagetes erecta genome, in whichgenes are closely linked to each other.

通过AFLP标记技术对亲本的分析，发现亲本间存在不低于3.96%的遗传背景差异，远较理论值高，说明万寿菊基因组中在雄性不育基因附近存在比较大的保守区域，该区域基因间存在着比较紧密的连锁关系。

In this present study, sterile hybrid progenies derived from optimal combinations guaranteed the protection of intellectual property. Meanwhile, inter and intra-specific hybridization using male sterility and molecular method for hybrid seed identification paved a new way for crossbreeding Tagetes erecta through male sterility.

本研究所选育出的优良组合子代全部是不育类型的杂种，有力地保护了自主知识产权，利用雄性不育进行种内和种间杂交以及分子鉴定杂交种的方法，开创了万寿菊利用雄性不育进行杂交育种的新途径。

Under this condition, tannase activity reached to 51.2 U/gds after 96 h of cultivation, which was 3.6 times as the conventional sterile fermentation.

在该条件下通过96 h的培养，单宁酶的活力可达51.2 U/gds，是常规灭菌发酵的3.6倍。

According to anther abortion characteristics and hormone functions, it was suggested that IAA, GA3 and ZR deficiency might be associated respectively with the inhibition of starch grain accumulation, pollen mother cell and tapetal cell expansion and tetrad formtion, and that abortion and even death of pollen mother cells and tapetal cells in sterile anther might be accelerated by high ABA accumulation.

根据内源激素的功能推测，不育花药IAA含量过低使花药淀粉积累受阻，GA_3含量不足影响花粉母细胞和绒毡层细胞的膨大，过低的ZR含量使花粉母细胞不能分裂形成四分体，过高的ABA含量促进花粉母细胞退化和死亡。

is that Tai Yu-D2 male sterile lines abortion occurs in monokaryon stage, the tapetal expanding abnormally occurs in dyadphase stage, pollen aborts completely, is a type of no pollen.

泰玉D2不育系花药绒粘层在二分体时期成辐射状膨大，小孢子在单核期败育，花粉败育完全，属无花粉类型。

The results shows that the tapetal expanding abnormally occurs in dyadphase stage, microspore abortion occurs in the early of monokaryon stage, disaggregation in the end of monokaryon stage, only some spall of microspore is observed in monokaryon stage, the four cell walls also exist, the tapetal cells became completely vacuolated, almost filled the whole locule. vascular bundle of male sterile line anther vanish at mature pollen stage.

结果发现花药绒粘层在二分体时期发生异常，小孢子在单核前期开始败育，至单核后期完全解体，花药发育后期不育系药腔中只观察到少量的小孢子残体，花药壁的四层细胞依然存在，绒粘层细胞已经彻底液泡化，占据了药腔的整个空间，花粉成熟期不育系花药维管束消失。

Microscopic observation of microsporogenesis of the male sterile lines revealed that abortion occurred mononuclear stage. The tapetal cells became higly vaculate, pressing the microsporocyte seriously, interfering the normal microsporpgenesis development and finally leading to pollen grain abortion.

进一步对其细胞形态学进行观察结果表明，ogura和改良型不育系败育时期发生在单核花粉期，绒毡层异常膨大，挤压小孢子正常发育，小孢子液泡化而导致败育，并且在花药发育过程中有一些异常现象发生。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.
